The i.p. administration of chemotherapy in ovarian and uterine serous carcinoma patients by biodegradable nanoparticles may represent a highly effective way to suppress peritoneal carcinomatosis. However, the efficacy of nanoparticles loaded with chemotherapeutic agents is currently hampered by their fast clearance by lymphatic drainage. Here, we show that a unique formulation of bioadhesive na...

In this thesis, the strength-enhancing mechanisms of dry binders in direct compression were studied. The systems investigated were binary mixtures containing various compounds and binders. Among the binders used were a series of different molecular weights of polyethylene glycol. The proposed simplified tablet model describing the fracture path in a tablet during strength testing offers an expl...

background: the poisoning is mostly due to suicide and is observed in younger age groups. the systemic manifestations of alp poisoning are common but pernicious manifestations of them are cardiotoxicity, shock, and ards. the clinical hallmark of cardiotoxicity is arrhythmia. the aim of this study was to investigate cardiac arrhythmias in patients poisoned with alp who were admitted to razi hosp...

the objective of this work was to develop and evaluate the levofloxacin hemihydrate floating formulations (f1-f9). selection of optimized batch was done by model dependent approach and novel mathematical approach. f1-f9 batches were prepared by direct compression method using gelucire 43/01 (hydrophobic) and hydroxypropylmethylcellulose (hydrophilic) polymer in different ratios. the floating ta...

in the current study, floating dosage form containing acyclovir was developed to increase its oral bioavailability. effervescent floating tablets containing 200 mg acyclovir were prepared by direct compression method with three different rate controlling polymers including hydroxypropyl methylcellulose k4m, carbapol 934, and polyvinylpyrrolidone. optimized formulation showed good floating prope...

background: aluminum phosphide or rice tablet is one of the most common pesticides which leads to accidental or intentional acute intoxication and finally death. in this paper, we describe a successful management of intoxication with rice tablet in a young girl. case presentation: a 14-year-old girl was admitted due to consumption of rice tablet. gastric washing with two vials of sodium bicarbo...

A new and simple method for testing and classifying the bioadhesive behavior of polymeric microparticles,with or without drugs is presented. The method is used to determine the adhesive forces between solid polymeric microparticles of diameter up to 200 pm in contact with natural rn~os~ or with a mucin gel. A t~oret~ul analysis is presented in order to calcu~te the ~~sive c~r~ter~tics of spheri...

Pharmacists have been splitting scored tablets to individualize and titrate dosages since the end of the pill-rolling era. We have generally accepted that scored tablets may be evenly divided, resulting in 2 half-tablets containing one-half of the whole tablet strength. Slight powdering is unavoidable, but it is generally accepted that loss of a few molecules of active drug is not likely to be ...

the effect of different kinds of surfactants in various concentrations incorporated in an inert matrix, on the release of procainamide hydrochloride, as a cationic model compound, was investigated in this study. sodium lauryl sulfate and sodium stearate as anionic surfactants, cetyl pyridinium chloride and cetyltrimethyl ammonium bromide as cationic and span 60 and tween 80 as non-ionic surfact...
